Problem with sorted search download

To all,

I've had 3.6.4 up and running for almost a year now and never noticed 

this problem. I created a search to sort by due date. The results were
sorted correctly. I then downloaded the results to a spreadsheet and the
results were in ticket id order, not due date order. This surprised me
to no end. I assumed that whatever the results of a search, they would
be downloaded in the same sorted order. Anyone have a clue to resolving
this? Is this corrected in 3.8? Thanks.
